Sonoff SenseGuard Presence Core 24G Human Presence Sensor (SNZB-06P24) – 24 GHz mmWave Radar Technology, Continuous Lux Sensor, 7 Detection Zones, Zigbee 3.0, USB-C Power Supply

Description

The Sonoff SenseGuard Presence Core 24G (SNZB-06P24) represents a major advancement in the SONOFF range of presence sensors. The switch to a new-generation processor and a 24 GHz mmWave radar module offers surgical precision in detecting human presence in a room, putting an end once and for all to those annoying situations where the lights switch off automatically whilst you’re reading, working on your computer or watching TV.

The SNZB-06P24 model brings essential improvements over previous generations: the integration of a continuous-measurement ambient light sensor in lux, the ability to divide the monitored space into 7 independent detection zones, and an intelligent algorithm for learning and filtering out interference. The 360° adjustable magnetic mount and Zigbee 3.0 connectivity enable rapid and ultra-stable integration into your Smart Home ecosystem.

Key Features & Technical Advantages

• 24 GHz mmWave Radar Technology (Micro-Motion Detection): Detects imperceptible movements of the human body (breathing, typing, subtle head movements). The sensor knows you’re in the room even if you’re completely still.

• 7 Configurable Detection Zones: Coverage ranges of up to 4 metres and 110° can be divided into 7 individual distance zones. You can enable or disable specific zones to avoid detection near open doors or in secondary passageways.

• Automatic Calibration and Interference Filtering (Spatial Learning): The built-in calibration function allows the sensor to learn its surroundings and ignore repetitive sources of non-human movement (ceiling fans, indoor air conditioning units, curtains moved by the wind).

• Integrated Ambient Light Sensor (Real Lux Reporting): Continuously measures the illuminance level in lux (not just a binary night/day status). Enables the creation of smart automations based on the exact brightness threshold in the room.

• Bluetooth & Zigbee 3.0 Configuration: Zigbee 3.0 connectivity ensures instant response times within the local network. In addition, the integrated Bluetooth module allows advanced detection parameters to be configured directly via the eWeLink app, even when the sensor is paired with third-party gateways.

• Continuous Power Supply via USB Type-C: To keep the 24 GHz mmWave radar active at all times without interruption, the sensor is powered directly at 5V DC via the USB-C port (cable included in the pack).

Usage Modes and Scenarios

1. Smart Lighting in the Office / Living Room: Set the LED strip and light fittings to switch on when you enter the room, keeping them on continuously whilst you are working at your desk. The lights switch off only 30 seconds after you have actually left the room.

2. Lux-Conditional Automation (Energy Saving): Programme the lighting to switch on when presence is detected only if the ambient light level falls below the 50 lux threshold (e.g. at dusk or on cloudy days).

3. Passage Zone Filtering (Custom Zones): Configure the sensor to monitor for presence only in Zones 1–3 (the sofa/TV area) and to ignore Zones 6–7 (the passageway next to the living room door), thereby preventing accidental switching on.
